BACKGROUND OF THE INVENTION

Artificial intelligence (AI), machine learning, and deep learning are utilized for various image processing tasks, computer vision tasks, and the like. Artificial intelligence as used herein refers to techniques that enable devices to mimic human intelligence, using logic, if-then rules, decision trees, and the like. Machine learning includes a subset of artificial intelligence that includes abstruse statistical techniques that enable machines to improve at task with experience. Deep learning includes a subset of machine learning that includes algorithms that permit software to train itself to perform tasks by exposing multilayered artificial neural networks, recurrent neural networks (RNN), convolution neural networks (CNN) or the like to vast amounts of data. For ease of explanation artificial intelligence, as used herein, also includes machine learning, deep learning and the like. Furthermore, as used herein the term images refers to pictures and video.

Referring to FIG. 1, a method of image capture and processing for use in artificial intelligence tasks, according to the convention art, is shown. Images are generally captured in a given format, such as frames of Red, Green and Blue (RGB) pixel data, referred to herein as the native format 110. The native format can comprise a relatively large amount of data that consumes a relatively large amount of communication bandwidth and or a relatively large amount of memory space to transfer and or store the image data in the native format. Therefore, the native format image data is typically converted to a transformed domain data format 120. For example, RGB pixel data can be converted into YCbCr discrete cosine transform (DCT) encoded components for transmission and storage. The transformed domain image data can then be transmitted and or stored 130 for subsequent processing by artificial intelligence tasks. Artificial intelligence tasks, however, typically process image data in a native format such as RGB pixel data. Therefore, the transformed domain data format is typically converted back to the native data format 140, before processing in artificial intelligence tasks 150.

Referring now to FIG. 2, an exemplary method of converting native format image data to transformed domain image data 120 according to the conventional art is shown. As illustrated, a frame of RGB image data 210 can include an array of red pixel values 212, an array of green pixel values 214 and an array of blue pixel values 216. Each value can be represented by eight bits. For example, frames of pixel data in the Red, Green and Blue (ROB) color space 210 can be converted 220 into frames of image data in the YCbCr luma-chroma color space 230. The frame of YCbCr image data 230 can include a luma component 232, a blue-difference chroma component 234 and a red-difference chroma component 236. The frames of YCbCr image data 230 can be domain transformed 240 utilizing a Discrete Cosine Transform (DCT) into components of discrete cosine transformed YCbCr image data 250. The discrete cosine transformed YCbCr image data 250 can include a discrete cosine transformed luma component 252, a discrete cosine transformed blue-difference chroma component 254, and a discrete cosine transformed red-difference chroma component 256. The above exemplary method of converting native format image data to transformed domain image data is merely for illustrative purposes. It is to be appreciated that there are other color spaces and or other transformed domains that can be applied.

Referring now to FIG. 3, an exemplary method of converting transformed domain image data to native format image data 140 according to the conventional art is shown. For example, discrete cosine transformed YCbCr image data 310 can be inverse domain transformed 320 into frames YCbCr image data 330. The frames YCbCr image data 330 can be converted 340 into frames of RGB image data 350.

Image capture in a native data format, conversion of the native formatted image data to a transformed domain format for transmission and storage, and then conversion back to the native format for processing in artificial intelligence tasks can also consume large amount of communication and processing resources. The increased communication and processing load can result in increased processing latency and or increased power consumption. Therefore, there is a continuing need for improved image capture and processing by Artificial Intelligence, machine learning, or deep learning tasks.

The system for determining the importance of encoded image components for artificial intelligence task will be further explained with reference to FIG. 6, along with FIG. 4 as described above. FIG. 6 shows a method of determining the importance of encoded imaged components. The method may be implemented as computing device-executable instructions (e.g., computer program) that are stored in computing device-readable media (e.g., computer memory) and executed by a computing device (e.g., processor). The method can include receiving components of transformed domain image data, at 610. The components of transformed domain image data can be received by the one or more processors 406 from the one or more image capture units 402 or one or more storage units 404 across the one or more communication interfaces 408-414. In one implementation, the components of transformed domain image data can be one or more frames of Discrete Cosine Transform (DCT) YCbCr image data components. In other implementations, the component of transformed domain image data can be components of frequency domain image data, components of Fourier Transform (FT) image data, components of Wavelet Transform image data, components of Discrete Wavelet Transform (DWT) image data, components of Hadamard transform image data, or components of Walsh transform image data, or the like. In one implementation, the received components of transformed domain image data can be generated from native format image data as described above with reference to FIG. 2.

At 620, the relative importance of the components of transformed domain image data can be determined by a component importance determining function 442 on the one or more processors 406 for a given artificial intelligence tasks. As previously stated, the use of the term Artificial Intelligence herein is intended to also includes machine learning, deep learning and the like. In one implementation, determining the relative importance of the components of the transformed domain image data can include gating the components of the transformed domain image data to turn on select ones of the components of the transformed domain image data for input to a Deep Neural Network (DNN) to determine the relative importance of the component of the transformed domain image data. In another implementation, determining the relative importance of the components of the transformed domain image data can include gating the components of the transformed domain image data based on a cost function to control select ones of the components of the transformed domain image data for input to a Deep Neural Network (DNN) to determine the relative importance of the component of the transformed domain image data. For example, the cost function can include a first term based on an error between a prediction and a target value, and a second term based on the number of active channels in accordance with Equation 1:

Cost=Loss(prediction, target)+λ#Proportion(active−channels)  (1)

In yet another implementation, determining the relative importance of the components of the transformed domain image data can include gating the components of the transformed domain image data in which more important components is more likely to be turned on than less important components for input to a Deep Neural Network (DNN) to determine the relative importance of the component of the transformed domain image data.

At 630, an indication of the relative importance of the components of the transformed domain image data can be output. In one implementation, the indication of the relative importance of the components of the transformed domain image data can be provided to the given artificial intelligence task for use in performing the artificial intelligence task on the components of the transformed domain image data.

Referring now to FIG. 7, a system for determining importance of encoded image components for artificial intelligence tasks, in accordance with aspects of the present technology, is shown. The system comprises a plurality of neural networks 702-710 configured to receive a corresponding ones of a plurality of transformed domain image data components 712-720. In one implementation, the transformed domain image data components can include 64 discrete cosine transformed luma Y components, 64 discrete cosine transformed blue-difference chroma Cb components, and 64 discrete cosine transformed blue-difference chroma Cr components.

The plurality of neural networks 702-710 can be configured to predict if the corresponding one of the plurality of transformed domain image data components 712-720 comprises an important component for an artificial intelligence task. If the transformed domain image data component is an important component, the corresponding neural network can generate a first indication. If the transformed domain data component is not an important component, the corresponding neural network can generate a second indication. In one implementation, the respective neural networks generate an indication of ‘1’ when the corresponding transformed domain data component is important, and an indication of ‘0” when the corresponding transformed domain data component is not important for a given artificial intelligence task.

The plurality of transformed domain image data components 712-720 can be gated 722-730 in accordance with the corresponding indication generated by the corresponding neural network 702-710. In one implementation, the plurality of transformed domain image data components 712-720 can be gated 722-730 by multiplying the corresponding indication from the corresponding neural networks 702-710. If the indication is a ‘1,’ the received transformed domain image data component 712, 718, 720 can be provided as in important transformed domain image data component 732, 738, 740. If the indication is a ‘0,’ the received transformed domain image data component 714, 716 can be blocked 734, 736. The indication of the importance of the transformed domain image data components is not limited to values of ‘1’ and ‘0’. In other instances, the indication can be a value between 0 and 1, wherein the higher the value the greater the importance of the transformed domain image data component.

Referring now to FIG. 8, exemplary components of the transformed domain image data, in accordance with aspects of the present technology, are illustrated. The exemplary components of transformed domain image data may be based on the ImageNet dataset. ImageNet includes more than 14 million images in more than 20,000 categories that have been annotated to indicate what objects are pictured. The neural network used to determine the importance of the transformed domain image data components can be the MobileNet_v2, which is a convolution neural network that has been trained on more than a million images from the ImageNet dataset. The luma Y components of the discrete cosine transformed image data can include an 8×8 matrix of 64 channels. Similarly, the blue-difference chroma Cb components of discrete cosine transformed image data can include an 8×8 matrix of 64 channels, and the red-difference chroma Cr components of discrete cosine transformed image data can include an 8×8 matrix of 64 channels. A value of the relative importance of the transformed domain image data components can be assigned to each channel value. In the illustrated example, channels 0-3, 8-11, 16-19 and 24-26 in the discrete cosine transformed luma Y components can have importance values greater than ‘0.’ Channels 0, 1 and 8 in the discrete cosine transformed blue-difference chroma, and channels 0, 1, 8 and 9 in the discrete cosine transformed red-difference chroma components can have importance values greater than ‘0.”

Referring now to FIG. 9, the relative importance of exemplary components of the transformed domain image data, in accordance with aspects of the present technology, are illustrated. The active channels, in the illustrated exemplary components of the discrete cosine transformed image data are mostly on luma Y channels 910, and partly on blue-difference chroma Cb channels 920, and red-difference chroma Cr channels 930. For the exemplary components of transformed domain image data based on the ImageNet dataset processed by the MobileNet_v2, using all 192 channels has been found to results in an accuracy of approximately 70%. In comparison, using 22 channels that are determined to be important can achieve an accuracy of approximately 69.3%. Accordingly, substantially similar accuracy can be achieved, while reducing the number of processed channels by 170.

Referring now to FIG. 10, method of computing an artificial intelligence task, in accordance with aspects of the present technology, is shown. The method of computing an artificial intelligence task will be further explained with reference to FIG. 11, which shows a processor for computing the artificial intelligence task. In one implementation, the processor 1100 can be one or more central processing units (CPUs), one or more cores of one or more central processing units (CPUs), one or more graphics processing units (GPUs), one or more cores of one or more graphics processing units (GPUs), one or more artificial intelligence accelerators, one or more vector processors, one or more memory processing units, or the like, or combinations thereof. In one implementation, the processor 1100 can include one or more compute units 1110, one or more controllers 1115, and integral memory 1120. In other implementations, the memory 1120 can be external to the processor 1100.

The method can include receiving components of transformed domain image data, at 1010. The components of transformed domain image data can be received by the memory 1120 of the processor 1100. In one implementation, the components of transformed domain image data can be received from one or more image capture or storage units. In one implementation, the received components of transformed domain image data can be generated from native format image data as described above with reference to FIG. 2. In one implementation, the components of transformed domain image data can be one or more frames of Discrete Cosine Transform (DCT) YCbCr image data components. In other implementations, the component of transformed domain image data can be components of frequency domain image data, components of Fourier Transform (FT) image data, components of Wavelet Transform image data, components of Discrete Wavelet Transform (DWT) image data, components of Hadamard transform image data, or components of Walsh transform image data, or the like.

At 1020, an artificial intelligence task can be configured to process the components of the transformed domain image data based on one or more gating flags. In one implementation, the one or more gating flags can be arranged in a vector of bits indicating corresponding flag states or values. For example, the vector of bits can indicate one or more on components of the transformed domain image data and one or more off components of the transformed domain image data. The vector bits can be read to accelerate hardware by reading and or processing turned on components of the transformed domain image data and skipping turned off components. In one implementation, the one or more gating flags can be based on one or more indications of available computational resources 1030. For example, when the current utilization of the processor 1100 is relatively low (e.g., below a threshold) the one or more gating flags can be configured for processing a larger subset of the components of transformed domain image data by the processor 1100. When the current utilization of the processor 1100 is relatively high (e.g., above a threshold) the one or more gating flags can be configured to for processing a smaller subset of the components of transformed domain image data. In another implementation, the one or more gating flags can be based on one or more indications of the relative importance of the components of transformed domain image data 1040. For example, the gating flags can be configured for processing a subset of the transformed domain image data components determined to be important by the processor 1100 for the given artificial intelligence task. In yet another implementation, the one or more gating flags can be based on the one or more indications of the relative importance of the components of transformed domain image data 940 and the available computational resources 1030. For example, when the current utilization of the processor 1100 is relatively low (e.g., below a threshold), the one or more gating flags can be configured for processing a larger subset of the important transformed domain image data components. When the current utilization of the processor 1100 is relatively high (e.g., above a threshold), the one or more gating flags can be configured for processing a smaller subset of important transformed domain image data components. The one or more gating flags can be dynamically adjusted based on changes in the available computational resources and or the importance of components of the transformed image data. Furthermore, the gating flags are not limited to representing available computational resource and or the importance of the transformed image data components. The gating flags can also represent any number of other factors related to the processing of the components of transformed domain image data for an artificial intelligence task.

In one implementation, the controller 1115 can include one or more channel switches 1125 and one or more micro-operation scheduler 1130. The one or more channel switches 1125 can be configured to receive the one or more gating flags computed by one or more compute units 1110. The one or more micro-operation controllers 1130 can be configured to receive instructions 1140, such as convolution commands, and generate corresponding micro-operations 1145 for execution by the one or more compute units 1110 to perform functions, such as convolution operations, for performing one or more artificial intelligence tasks. The one or more micro-operations schedulers 1030 can also be configured to generate addresses 1150 for transferring data, such as components of transformed domain image data 1155, into the memory 1120. The one or more micro-operations scheduler 1130 can also be configured to generate addresses 1150 for transferring data, such as components of transformed domain image data 1155, for corresponding micro-operations to the one or more compute units 1110. The one or more channel switches 1125 can be configured to selectively control the generation of micro-operations 1145 and addresses 1150 by the one or more micro-op schedulers 1130 based on the one or more gating flags 1135 from the one or more compute units 1110. In one implementation, the one or more channel switches 1125 can cause the one or more micro-op scheduler 1130 to generate micro-operations 1145 to multiply the state of a corresponding gating flag with a corresponding transformed domain image data component. For example, if the corresponding gating flag is a ‘0’ indicating that the component is not an important component and or there is not enough processing resources to utilize the component, the corresponding micro-operation 1145 can multiply the corresponding gating flag with the corresponding transformed domain image data component resulting in a corresponding transformed domain image data component of all zeros, making subsequent computations easier to perform. If the corresponding gating flag is a ‘1’ indicating that the component is an important component and or there are enough processing resources, the corresponding transformed domain image data component is fed to subsequent computations unchanged. Alternatively, the one or more channel switches 1125 can cause the one or more micro-op schedulers 1130 to skip the generation of corresponding micro-operations 1145 and addresses 1150 when the corresponding gating flag is a “0” such that the one or more compute units 1110 do not have to perform operations with respect to the corresponding transformed domain image data component. After performing the received instructions 1140, such as the convolution commands of a given artificial intelligence task, the processor 1100 can output results of the artificial intelligence task, at 1050.

Accordingly, performing artificial intelligence tasks can be performed on a subset of transformed domain image data components based on one or more factors such as available computational resources, the importance of the components of the transformed domain image data, and the like. Artificial intelligence tasks can also be performed directly on the components of transformed domain image data, which can also advantageously reduce computational workload, data transmission bandwidth, processing latency, power consumption and or the like because the components of transformed domain image data does not need to be converted back to the native image data format before performing the artificial intelligence tasks. Performing artificial intelligence tasks only on a subset of the components of transfonned domain image data found to be more important than other components of the transformed domain image data can also further reduce computational workload, data transmission bandwidth, processing latency, power consumption and or the like. Performing artificial intelligence tasks only on the subset of the components of transformed domain image data found to be more important than other components of the transformed domain image data has been found to achieve almost equal accuracy as compared to performing the artificial intelligence task on the native format image data.
